Thanks for the quick response. I should have known better...
I'm on CentOS 7.x (I'm not sure exactly. I don't maintain it):
$ uname -a
Linux scone 3.10.0-514.16.1.el7.x86_64 #1 SMP Wed Apr 12 15:04:24 UTC
2017 x86_64 x86_64 x86_64 GNU/Linux
I'm using gcc-7.2.0 which I built myself.
$ g++ --version
g++ (GCC) 7.2.0

I'm using qtbase, qtdeclarative, qtquickcontrols, qtscript, and qttools.
All from the head revision of their 5.9 git branches and built with
compiler above.
$ qmake --version
QMake version 3.1
Using Qt version 5.9.3 in /opt/segdeps/gcc/lib
I haven't done a git clean but I always do out-of-source builds and the
git clones are recent.
Would any other information be useful?
What version of Qt do you build against?
